Comparative Losses of Glyphosate and Selected Residual Herbicides in Surface Runoff from Conservation-tilled Watersheds Planted with Corn or Soybean.

The article presents a study to determine if the use of glyphosate instead of residual herbicides used in corn production results in reduced losses of herbicide in surface runoff in the U.S. The study applied the herbicide to chisel-plowed and no-till watersheds. The study reveals less losses of atrazine, alachlor and linuron when glyphosate was applied to all tillage practices. It notes that glyphosate-tolerant corn planting and soybean using glyphosate reduces the impact of the production of corn on surface water quality.
